If A9s and A6s get all the chips in before the flop, A9s owns 66.46% of the pot in the long run and A6s owns 33.54%. ## A9s against A6s: the numbers **Exact preflop results for A9s against A6s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | A9s | 59.608 | 13.707 | 26.685 | 66.461 | | A6s | 26.685 | 13.707 | 59.608 | 33.539 | Both hands are suited hands: A9s and A6s. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. That is a clear edge, 66.46% to 33.54%, but A6s still wins often enough that one hand proves nothing. About 13.71% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. For context, A9s sits at number 18 of 169 starting hands and A6s at number 31 when each is run against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | A9s | 12,248,000 | 2,816,000 | 5,483,000 | | A6s | 5,483,000 | 2,816,000 | 12,248,000 | Exact total: 12 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate. **A9s against A6s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | A9s | 1.982 | 1.678 | 3.747 | 0.505 | | A6s | 0.505 | 3.747 | 1.678 | 1.982 | In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity. ## Who is ahead on which flops Split by what the flop looks like, A9s peaks at 69.90% on rainbow flops topped by a ten or better and bottoms out at 61.84% on monotone flops. A9s stays ahead on all five textures. **A9s against A6s by flop texture, in percent** | Flop | Share of flops | A9s wins | Ties | A6s wins | A9s equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 24.526 | 63.151 | 13.504 | 23.345 | 69.903 | | Rainbow, nine or lower | 6.383 | 65.229 | 1.906 | 32.865 | 66.182 | | Two-tone | 46.543 | 61.638 | 9.970 | 28.392 | 66.623 | | Monotone | 5.215 | 56.780 | 10.118 | 33.102 | 61.839 | | Paired | 17.333 | 47.924 | 29.455 | 22.621 | 62.651 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand The table below sets each hand against its own random-hand baseline: a change of +3.68 points for A9s, from 62.78%, and -26.37 for A6s, from 59.91%. **A9s and A6s here compared with each against a random hand, in percent** | Case | Equity here | Against a random hand | Change in points | Times the random-hand equity | | --- | --- | --- | --- | --- | | A9s, all flops | 66.461 | 62.781 | +3.680 | 1.05862 | | A9s, rainbow, ten or higher | 69.903 | 62.781 | +7.122 | 1.11344 | | A9s, rainbow, nine or lower | 66.182 | 62.781 | +3.401 | 1.05417 | | A9s, two-tone | 66.623 | 62.781 | +3.842 | 1.06120 | | A9s, monotone | 61.839 | 62.781 | -0.942 | 0.98500 | | A9s, paired | 62.651 | 62.781 | -0.130 | 0.99793 | | A6s, all flops | 33.539 | 59.906 | -26.367 | 0.55986 | | A6s, rainbow, ten or higher | 30.097 | 59.906 | -29.809 | 0.50240 | | A6s, rainbow, nine or lower | 33.818 | 59.906 | -26.088 | 0.56452 | | A6s, two-tone | 33.377 | 59.906 | -26.529 | 0.55716 | | A6s, monotone | 38.161 | 59.906 | -21.745 | 0.63701 | | A6s, paired | 37.349 | 59.906 | -22.557 | 0.62346 | ## Does a shared suit matter? The hands cannot hold a suit in common here, which leaves a single case and a single number: 66.46% for A9s. **A9s against A6s by suit overlap, in percent** | Deals | Specific deals | Share of deals | A9s wins | Ties | A6s wins | A9s equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 59.608 | 13.707 | 26.685 | 66.461 | ## How often this matchup comes up How often does it happen? 12 of the 1,624,350 ordered deals (0.0007%) are A9s against A6s, and 24 (0.0015%) if either hand may sit in either seat. ## A worked example Take a $200 pot built from $100 each. A9s' equity of 66.46% is worth $132.92, a $32.92 edge, and A6s' 33.54% is worth $67.08, which is $32.92 under its stake. In 1,000 deals of exactly this matchup, expect about 596 won outright by A9s, about 267 won outright by A6s and about 137 split. ## The same matchup from the other side The reversed view, A6s against A9s, shows 33.54% for A6s and 66.46% for A9s.
